Bamburi Cement Plc has announced that it will stop production of Ordinary Portland Cement (OPC) within its product line from January 1, 2024, as part of its commitment to decarbonizing its operations.
“Withdrawing OPC from the construction sector is critical to greening and decarbonising the industry. In combination with the thrust on the use of eco-friendly cement offerings, it gives us the opportunity to onboard our partners and customers in our unstoppable journey to net-zero,” said Bamburi Cement MD, Mohit Kapoor.
- OPC is used in large infrastructure projects and high rise buildings.
- It typically contains 95% clinker, an intermediate material in the manufacture of cement produced by burning limestone and other materials in a kiln where CO2 is invariably released in the process.
- It emits the highest greenhouse gases into the atmosphere during its manufacturing and production.
One ton of clinker emits around 0.83 tons of CO2 into the atmosphere, according to Global Cement and Concrete Association (GCCA) regional data, whereas one ton of OPC emits approximately 0.79 tons of CO2, driving the building industry’s 8% (2.8 billion tons) of carbon emissions globally.
The commitment, which comes amid the ongoing 2023 United Nations Framework Convention on Climate Change (COP28) in United Arab Emirates, accelerates the company’s sustainability target to 100 percent green products by 2025, decreasing carbon (CO2) emissions to fight climate change.
Kapoor said it will affect the production of Powerplus cement, used in medium to large construction projects but will have no disruptive impact on customers due to presence of alternative greener products.
As an alternative, the company said in a statement it has a range of eco-labelled cement products with low carbon emissions, according to the company’s Head of Innovation and Technical Services, Eng. Fidelis Sakwa.
“Our flagship eco-labelled product Bamburi Duracem 42.5 cement reduces carbon emissions by 64% in comparison to the OPC. Duracem was successfully used to build the Makupa Bridge in Mombasa resulting in a saving of 10 million kg of CO2 as compared to OPC that would have been used,” said Sakwa.
He added that Bamburi Cement’s technical team has invited contractors for consultative opportunities on providing viable options including conducting project specific concrete mix designs with a lower carbon footprint in the near term.
